Protein Tag: N-His-SUMO
Uniprot: P20963
Accession: P20963
Background: CD247, also known as CD3-ZETA, belongs to the CD3Z/FCER1G family. It contains 3 ITAM domains. As a-cell receptor zeta, CD247 forms the T-cell receptor-CD3 complex together with T-cell receptor alpha/beta and gamma/delta heterodimers, and with CD3-gamma,-delta and &ndash,epsilon. The zeta chain plays an important role in coupling antigen recognition to several intracellular signal-transduction pathways. Low expression of the antigen results in impaired immune response. Two alternatively spliced transcript variants encoding distinct isoforms have been found for CD247 gene. Defects in CD247 can cause immunodeficiency due to defect in CD3-zeta. An immunological deficiency characterized by T-cells impaired immune response to alloantigens, tetanus toxoid and mitogens. CD247 may play a role in assembly and expression of the TCR complex as well as signal transduction upon antigen triggering.
Bio Acitivity: Not validated for activity
Sequence: Arg52-Arg164
Purity: > 85% as determined by reducing SDS-PAGE.
Formulation: Lyophilized from sterile 20mM Tris-HCl, 150 mM NaCI, 1 mM DTT ( pH 8.0), Mannitol, Proclin300, Tween 80
Normally 5%-8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
